[NOTES]
[ 1] I take the opportunity to thank M. J. B. Teran, who undertook to edit these chapters, and to express, with him, my satisfaction that events have falsified his rather pessimistic predictions as regards the author.

[5] F. de Azara, Diario de un reconocimiento de las guardias y fortines que guarnecen la linea frontera de Republica Argentina (1796, Coll. de Angelis, vol. vi.). The documents collected by de Angelis show clearly that there had been some idea in the middle of the eighteenth century of occupying the whole plain to the east of the Sierra de Tandil. These ideas of expansion, of which D'Azara's plan is another instance, were interrupted by the Revolution (Diario de D. Pedro Pablo Pabon, Coll. de Angelis, iv. etc.).
[6] M. J. Olascoaga gives (La conquête de la Pampa: Recueil de documents relatifs à la campagne du Rio Negro, Buenos Aires, 1881) valuable documents concerning both the details of the fight with the Indians and the distribution of their invernadas (common lands) in the region of the Pampas. Olascoaga translates it "winter quarters"; it was pasturage on which they kept their cattle and from which they set out on their expeditions.
